Investigations of Hydrogenated Amorphous Silicon by High Resolution NMR of 29Si

Abstract

The new techniques of high resolution NMR in solids on “rare” spins via cross polarization and proton spin decoupling introduced by A. Pines, M.G. Gibby and J. Waugh, combined with the rapid rotation of the sample at the magic angle have been applied to amorphous hydrogenated silicon. These experiments can give structural informations on these materials and on their amorphous nature. First results will be presented.
